Tooling materials science| Резюме: | The abrasive ability of a staurolite mineral concentrate of 160/125, 125/100 grain size produced by Vilnohirsk Mining and Metallurgical Combine is determined and comparative data of the abrasivity of AC6 125/100 synthetic diamond powder is indicated. Determination of abrasive ability of samples was carried out on the UAS-2M equipment (design of the ISM NASU) according to the "Method for determining the abrasive ability of grinding powders of synthetic diamonds using a special grinding composition".
The production potential of the effective use of natural mineral granular concentrates in the working layer of diamond wheels as the supporting elements to improve the operational characteristics of grinding wheels during the grinding process was analyzed. The results of the studies of the abrasiveness of staurolite concentrate samples have shown that the staurolite can be used in compositions for the production of special types of tools and pastes intended to achieve high-quality surface treatment. Adding staurolite concentrate to a binder of diamond-abrasive wheels results in the considerable (up to 25 %) saving of superhard materials (diamond and cubic boron nitride) and thereby reduces the cost of the wheels. That considerably affects the technical and economic performance of machining, as well as improves the quality of the processed surface. |
